To Inkom z't may concern.'

new and'- useful Improvements in Scrubbing-Machines, of which thefollowing is a specification.

invention relates to improvements in scrubbing machines, and theprincipal object of the invention is to provide a mechanism which may bereadily adjusted to suit conditions, and operated'manually with amoderate expenditure of-muscularlabor.

' Another object .is tol provide a scrubbing device which may -beelectrically driven, the l brush or scrubbingelements being movablelaterally and vertlcally :while rotating, and finally, to provide meanscombined with the mechanism which will supply a -current of water orcleansing solution.

These and other like objects are attained by the novel construction andcombination of parts hereafter described .and shown in the'accompanyindrawings, forming a material part of t is specification, and in whichFigure 1 is a side` elevational view of an apparatus made in accordancewith the -in-v vention.

Fig. 2 is a to plan view of the same.A Fig. 3 is a agmentary sectionalVview taken on line 3 3 of Fig. 1.

Fig. 4 is another enlarged side elevational view showing in detail someof the moving parts in various positions. l Fig. 5 is an enlargedsectional view taken on line 5 5 of Figs. 1 and 4, and

Fig. 6 is a partial side elevational Aand sectional view of the air pumpand watersu ply tank..

eferring now more particularly to Fig. 1, the apparatus is shown inoperation on a pane of glass 11 mounted in a window frame, set in thesash 12, the window frame 10 being supported in a V.Wall or partition 14contiguous to the floor 15.

The apparatus consists of a circular base 16, supported upon a vtripodhaving three legs 17, equally spaced and provided with rollers 18, bymeans of which the apparatus may be trundled along from place to placeas desired.

Engaged centrally in the base 16 is a coarsely threaded screw 20, thesame supporting a 'rotatable superstructure 22, and

carrying oppositel disposed standards 23, 1n which is rotata ly mounteda horizontal shaft 24, which is also limitedly slidable within thebearings.

Rigidly attached' to the shaft 24,midway of the standards 23, is a plate25,. having an upwardly extending` arm 26, and having formed with it anextending lateral hub 27,l in whichthe shaft 28 is'rotatably mounted,

the same being held against longitudinal disi placement by the collar 29at one end,'and the hub 30 of the sprocket 32 at the other, b oth collarand hub being` secured by pins rlgidly to the shaft, the same beingrotatable crimen..

by means of-the handle 33 ailixed on the sprocket 32. v At the outer endof the shaft 24 is secured ahead 34, the head being reduced in-thicknesscat its outer end and carrying a bearing inf which islpivotally mounted a shaft 35,` to one endfof which is alixed'anotherspropket-v36 engagedb the chain or l1ke driving element 38 wit thedriving sprocket 32, sorthat the shaft35 and spur pinion 40 secured uponitmay be rotated;

Also on the shaft 35 is pivoted a clevis 42, the two sides of whichengage the head andmay be secured thereto by means of a tapered pin 43,the same vpassim throu h a hole formed in the head 34, t us loc g Ytheclevis andhead. rigidly together. Formed transversely wlth the clevisarms 42 is an elongated guide 45, in which is slidably mounted a rack46, the teeth of which mesh with the teeth of the pinion 40 so that asthe latter is rotated reciprocating motion `may be transferred to therack, which, as

will be seen, is maintained at right angles to the axis of the shaft 24when in an operative position, although it is possible, by removing thepin' 43 and'rotating the clevis 42 uponl the shaft 35, to turn the rack46 parallel with the shaft 34.

Ailixed to the extreme upper end of the rack 46 is a bracket 48,supporting a motor 50, and attached to'the shaft 51 is a stem 52carrying the rotatable brush 55, an electric current being supplied tothe motor 50 through the insulated 'cord 56, the opposite end of whichmay be engaged with a terminal plug 57, attached to the wa1114 orotherwise as, may be convenient.`

Should, however, an electric current be unobtainable, the brush stem 52maybe attached to the rotatable shaft 60, carried in the 'bracket 48alongside the motor, in suit-A outer end 67- arranged conveniently tobe' operated by the foot, water for moistening or rinsin the windowbeing provided by the head 70, the same having a plurality of fineperforations and being engaged by the tube 71, also carried at its outerend by the rack 46, communicating with which is aflexible hose 72,controlled by the valve 73, the same being secured to the exterior ofthe tank 75 on the latform 22, and. which is provided with a4 llingopening 76.

Also formed in the tank 75 is a cylinder 78, in which is slidablyengageda plunger 79, actuated by thenrod 80, which extends y upwardthrough the cover plate 82 and is provided with -an operating handle 83,the

same acting as a `suction pump, the intake 85 of which is formed throughthe platform 22 and controlled by a fiat valVe'S, so that as the plunger79 is raised, a current of air passes into the cylinder 78, while duringthe downstroke, the valve 8 6 closes the passage 85, which forcesl the'air into an adjoining chamber 88 controlled by the valve 89, controllingthe passage of air through the cham# ber 88, permitting it to ascendinto the space 90 formed in the tank 75,',so as to force the liquidcontents out through the pipe 72.

In operation, the tank 75 having been filled with the cleansing solutionit is -desired to'use, the apparatus is moved closely adjacent to thewlndow or other part, the rack and motor being extended substantiallyhorizontal, as indicated best in Fig 4, so as to project out through therelatively small opening between the sash and the window resaca@ sill;the rack is then raised vertically and held in position by the pin 43,connections being made with the electric current; the brush is pressedagainst the window pane by moving the apparatus slightly outward ordrawing the shaft 24 in such manner as to cause contact; water in anysuitable quantity may be released from the tank 7.5 by.

operating the valve 73, and the brush caused to traverse the part to becleansed by operating the handle 33, thereby causing thev brush to movevertically up or down, or by rotating the shaft 24, as by grasping thebar 2.6, it maybe moved laterally as well.

Thus any desired combination of. movelments mav begiven the brush so asto' cover the entire are-.twithin the range of the apparatus, and itwill be obvious that should electric current not be accessible the brushmay be operated by means of the foot lever b1, with entire facility. A

1t will also be noticeable that should the extent that water is notforced out through the head 70, that the pressure can be increased bymanipulating the handle 83.

having thus described my invention, what I claim as new, and desire tosecure by Letlmeans for rotating said head upon the axis of said shaft.y j
